Nolan and John S. Gilles, Louisville, Ky., assignors to Reynolds Metals Company, Richmond, Va., a corporation of Delaware Filed Dec. 4, 1963, Ser. No. 328,790 9 (Ilaims. (Cl. 49-449) This invention relates to an edgewise movable wall closure construction, and method of making the same. The invention, for example, is applicable to a door construction, window construction or any other similar closure construction.

The various frame members, outer panel rails and fastener receiving channels advantageously may be made of extruded material, such as of suitable extrusion aluminum alloy. The extrusions are so made that the frame and the panels in the frame cooperate in a manner which provides many advantages which will become apparent as the description proceeds.

According to thisinvention a rectangular frame may be provided which may be suitable as a door frame, window frame, and the like. A pair of rectangular panels are relatively movable parallel to and adjacent each other in the frame. Each of the panels may be mountable in the frame in a first position, so that, for example, one of the panels may be a stationary panel, if desired, and may be located at the left hand side of the frame, looking outwardly. The other panel may be movable parallel and adjacent to the stationary panel and may, for example, be at the right hand side of the frame when such movable panel is fully closed. The panels are so constructed that the panels may be rotated or positioned 180 about their respective vertical axes relative to their first positions, while they are outside of the frame, and then may be mounted in the frame with the result that the stationary panel is then at the right side of the frame, and the movable panel is at the left side of the frame.

The constructions of the frame and of the rails of the panels are such that they may be readily extruded from any suitable material, such as a suitable extruding aluminum alloy and the like, and yet the panels and frame may be selectively assembled, so that they may have the foregoing relative positions of stationary and movable relationship.

Another feature of this invention is that each of such a pair of relatively movable panels may have a meeting rail with a pair of inner central panels or glazed panel holding flanges, and with a pair of outer interlockable flanges. A first interlockable flange of one of the panels may interlock with a first interlockable flange of the other panel when the panels are mounted in the frame in their first position. However, when the panels are rotated or positioned 180 about their vertical axes outside of the frame, then they may be mounted in the frame with the second interlockable flange of one of the panels interlocking with the second interlockable flange of the other panel. Under these conditions, the movable panel may be movable leftwardly to open the door or window in their first position, whereas the movable panel may be rightwardly movable to open the door or window, when they are assembled in their second position.

Another feature of this invention is that the pulling rail of the movable panel may have a latch with a handle which is selectively insertable into the latch from either side of the pulling rail, so that the movable panel may be actuated by the handle and may be locked by a companion locking lever which also is insertable from either side of the pulling rail. In this manner the movable panel may be provided with a latch handle, and a latch locking lever, on the inside portion of the pulling rail.

Another feature of this invention is that one of the panels may be provided with a jamb rail, which has a locking flange to hold one of such panels stationary, while the other panel may remain relatively movable thereto.

Another feature of this invention is that each of the panels may have extruded rails on all four sides with each rail having glazed or central panel holding flanges.

Other features of this invention are apparent from this description, the appended claimed subject matter, and from the accompanying drawings, in which:

According to this invention, two relatively movable panels 10 and 12 are relatively movable with respect to each other when mounted in the frame 14. The panels 10 and 12 are mountable in the frame 14 in a first position, such as indicated in FIGURES 1 and 2. However, these panels 10 and 12 are also mountable in the frame 14 in a second position, such as shown in FIGURES 3 and 4, in which second position the panels 10 and 12 may be considered to have been rotated or positioned 180 relatively to the first position about respective vertical axes of the panels and 12.

When the panels are in the first position of the FIG- URES 1 and 2, the movable panel 10 is movable leftwardly from its closed position of FIGURE 1, to its partially opened position of FIGURE 2 or to a fully opened position. On the other hand, when the panels are mounted as shown in FIGURES 3 and 4 within the frame 14, then the movable panel 10 is movable rightwardly from the closed position shown in FIGURE 3 to the partially opened position shown in FIGURE 4 or to its fully opened position.

The constructions of the rails of the panels 10 and 12 and of the right and left jambs 16 and 18, the sill and top head member 22 of the frame 14 are such that the panels 10 and 12 may be rotated or positioned 180 about respective vertical axes between two selective positions, shown respectively in FIGURES 1 and 3, while they are outside of the frame 14, and may be assembled selectively in the frame to have the movable panel 10 move toward the left from its closed position to open its passageway, as in FIGURES 1 and 2 or toward the right, as in FIGURES 3 and 4.

The latch hardware on the movable panel 10 may be symmetrical and of a well known construction, so the latch handle 24 and latch lock lever 26 may be assembled in the latch to place them on the inside of the pull rail of the movable panel 10 when the. panel 10 is assembled in the frame 14 in either of the positions shown respectively in FIGURES 1 and 3.

The advantages of this invention may be utilized whether the panels 10 and 12 are actually rotated about their respective vertical axes or not. The panels may be permanently positioned and installed either as shown in FIGURES 1 and 2 or in FIGURES 3 and 4 without actually rotating the panels. However, the panels 10 and 12 may initially be installed, for example, in the positions of FIGURES 1 and 2 and then later they may be removed from the frame 14, rotated 180 about their respective axes, and then may be installed in thepositions of FIGURES 3 and 4, or vice versa, as the user may desire, for example, to accommodate changes in furniture arrangements and the like.

The frame members 16, 18, 20 and 22 may be extruded, one piece, homogeneous members which may be secured to each other in an effective manner. The side frame members 16 and 18 may be symmetrical with each other to receive the panels 10 and 12 and screen panel 72 as shown in FIGURES 1 and 3. The extrusions may be cut to desired lengths and desired end shapes to cooperate with the bottom sill 20 and the top member 22. The sill 20 and top member 22 may be cut to proper lengths likewise to join with the side members '16 and 18 at the corners, as is readily understood from the drawings.

The side frame members 16 and 18 may each include a main base member 24, screw receiving channels 26' and 28, inward flanges 30, 32, 36 and 38 and outward flanges 40 and 42.

The flanges 40 and 42 may be used to engage the wall opening edge in which the closure member is installed.

The flanges 30, 32, 36 and 38 may be used to cooperate with the panels which are installed in the frame 14.

For example, the flange may be provided with a seal receiving cavity 44 to receive the seal 46 slidingly to be engaged by the rails of the movable panel. The flange 32 may be provided with the seal receiving cavities S0 and 52 to receive the rails of panels 10 and 12. The cavities 50 and 52 may receive seals 56 and 58 of any well known type, such as the bristle type of seal 56 or the flexible bead type of seal 58, or vice versa.

The jamb rail 54 of panel 12 may have central panel holding flanges 60 and 62 which may have latch clip receiving flanges 64 and 66. One or more latch clips 68 may be hooked into a flange 66 or 64 and may be secured by a screw 70 to the base member 24'. This permits the panel 12 to be made into a stationary panel which is stationarily held by clip 68. The jamb rail 54 may be held by flange 36 on its other side.

The flanges 38 and 42 form the outer trim for the frame 14. The screen panel 72 may be received by the flanges 36 and 38 as it travels or rolls from side to side of frame 14 to cover the closure space which is opened and closed by the movable panel 10.

The right and left jambs 16 and 18 may be secured to the sill 20 and top member 22 at the corners of the frame 14 by screws 74 and '76, FIGURE 5, which are threadedly secured in screw receiving channels 28 and 26', FIGURES l and 3, respectively. The ends of the frame members 16, 18, 20 and 22 may be properly cut to make proper corner engagements as is readily understood from the drawings.

The fixed panel 12 may be made from the parts shown in FIGURE 6. It may include the extruded, one piece, homogeneous jamb rail 54, top rail 78 meeting rail 80 and bottom rail 82. These have, respectively, the inward central panel holding flanges 60, 62, 84, 86, 88, 90, 92 and 94. Additionally, the top rail has outward flanges 96 and bottom rail has outward flanges 98. The flanges 98 may have seal receiving channel 100 for flexible seals 102. The top rail 78 and bottom rail 82 have screw receiving flanges 104 and 106.

The rails 54, 78, 80 and 82 are inwardly movable to have their respective central panel holding flanges 60, 62, etc., engage and hold the central panel 108, which, if desired, may be a glazed panel as elsewhere described. The rails 54, 78, 80 and 82 may be secured together adjacent the corners of the panel 12 by the screws 109 which enter the openings 110 and threadedly engage the screw receiving channels 104 and 106.

The panel holding flanges 60, 62, etc., may hold the central panel 108, which, if desired, may be interchangeably either of the single glazed type of FIGURES 6, 7 and 9 or of the double glazed type of FIGURES 15 and 8. Either the single or double glazed ifttype may be interchangeably used in all of these embodiments and figures.

The panel 108 includes the glazing channels 112, 114, 116, 118 and 120, which receive the glazed paneling construction 122, which may be either a single or double glazed construction. (The words glass, glaze, glazed, are used herein as generic terms for any transparent material which is the equivalent of glass, such as transparent plastic, and the like.)

The channels 112120 may be made from a single longitudinal piece which maybe partially slitted transversely at 121 to wrap around the corners 125 of panel 108 and have the end pieces 118 and 120 meet at the joint 124. The longitudinal piece which forms the channels 112, 114, 116, 118 and 120 may be molded, extruded, etc., from any suitable material, such as rubber, plastic and the like. Such piece may be slitted at 121 to cut the channels up to the end bead 127, which may be made as a flange arresting bead and which may be continuously wrapped around the sides and corners of the paneling construction 122, as shown in FIGURE 6.

The rails 54, 78, 80 and 82 may have their respective central panel holding flanges 60, 62, etc. forced over the glazing channels by a procedure similar to that illustrated in FIGURE 9 wherein a suitable tapping block 126 may be placed on the outer flat face 129 of the respective rail and may be tapped in by any suitable tool such as hammer 128 or the like, after which the screws 109 may be threaded into the channels 104 and 106. This procedure firmly holds the central panel 108 within the joined rails 54, 78, 80 and 82.

Suitable, outward locking beads 130 may be formed on the flanges 132 of the glazing channels 112, 112A, etc. The flanges 60, 62, etc., of the rails 54, 78, 80, 82, and other rails elsewhere described in connection with the movable panel 10 may have inward beads 134 with inward slanting hooks which can be forced over the outward beads 130 during the operation shown in FIGURE 9 and which then interlock with the outward beads 130 in panel holding relationship.

The glazing channels 112, 112A, etc., may be made with one end bead 127 and with one or two outward beads 130. Likewise the panel holding flanges 60, 62, 84, 86, and other similar panel holding flanges elsewhere described may be made with one or two inward beads as elsewhere described or shown. These beads are so related to each other that if one inward bead only is provided on a flange it will select and lock with one bead 130 and abut against the end bead 127 as shown in FIGURE 5. However, there may be two outward beads 130, and one end bead 127 provided for the glazing channel and two inward beads 134 for the panel holding flanges 60, 62, etc., as shown in FIGURE 1 and elsewhere that also cooperate in holding relationship. Under these latter conditions, two inward beads 134 will cooperate with two outward beads 130 and an end bead 127 to provide the locking action shown in FIGURE 1. Therefore, an interchangeable relationship between the two outward beads 130 and the single or double inward beads 134 has been provided so the glazed panel channel may be assembled with the various side rails, top rails, and bottom rails which are used and are illustrated in the various figures.

In FIGURE 6, the top rail 78 and bottom rail have single inward beads 134 on flanges 84, 86, 92 and 96 and such single inward beads 134 can cooperate with the two outward beads 130 and end bead 127 as illustrated in FIGURE 5. Also, the meeting rail 80, in FIGURES 1 and 6, has flanges 88 and with two inward beads 134 which cooperate with two outward beads and an end bead 127 to lock the inner panel 108 to this meeting rail construction. The jamb rail 54 has a similar flange, channel and bead construction as shown in FIGURES 1 and 8.

The movable panel 18 may be assembled as shown in FIGURE 7 taken in connection with FIGURE 1, in which many of the details are somewhat similar to those described in combination with FIGURES 1 and 6. The panel 10 has the extruded, one piece homogeneous top rail 136, pull rail 48, jamb rail 138 and bottom rail 140.

The central panel 142 may be identical with or similar to central panel 108. Likewise, the rail flanges 144 of rails 48, 136, 138 and and their bead constructions 146 of the movable panel 10 may be identical with or similar to the various rail flanges 60, 62, 84, 86, etc., and their head constructions elsewhere described in connection with FIGURES 1 and 6.

Likewise the glazing channels 148 and their beads 150 of FIGURES 1 and 7 may be similar to the glazing channels 112120 and their head constructions elsewhere described in connection with FIGURES 1 and 6. Hence, description of these details will not be here repeated, and only the differing details will be described.

The meeting rail 80 of stationary panel 12 has interlocking flanges 152 and 154 outside of flanges 88 and 90, FIGURES 1 and 6. The meeting rail 138 of movable panel 10 has interlocking flanges 156 and 158 outside of its glazing channel holding flanges 144. When the panels 10 and 12 are in their first position, shown in FIGURE 1, the interlocking flanges 154 and 156 are interlocked whilethe interlocking flanges 152 and 158 are separated. However, when the panels 10 and 12 have been rotated or positioned 180 about their vertical axes to assume the positions of FIGURE 3, then the interlocking flanges 152 and 158 are the interlocked flanges while the interlocking flanges 154 and 156 are separated. The latch handle 24 and locking lever 26 have been removed from their position adjacent wall 160 of pull rail 48 in FIG- URE 1 and have been inserted adjacent the wall 162 of pull rail 48 in FIGURE 3. Thus the movable panel 12 has been changed from a leftwardly openable panel 6 in FIGURE 1 to a rightwardly openable panel in FIG- URE 3, as considered from the inside of the closure construction.

The interlocking flanges 152 and 154 have tapered ends 166 to form a bayonette joint with the substantially straight interlocking flanges 156 and 158 which have engaging enlargements 168 at their ends. The flanges 152 and 154 may have seal receiving cavities which may re ceive seals 170 which may be of the bristle type, if desired, and which form vertical seals against the outside atmosphere, as shown. Vertical seals are also formed by the jamb 48 With seals 46 and 56.

The screen panel 72 may be a rectangular panel with a rectangular rail construction including side rails 172 and 174, with rail 174 having an outer handle 176 and a combined handle and latch 178 which latches to the stationary latch member 180 which is attached to the frame side wall 24 by a screw 182, which may be transferred to the other side wall 24.

If desired, the handle 176 and latch 178 may be interchangeable so they may be placed in the positions shown in FIGURES 1 and 3, depending on the positioning of the panels 10 and 12.

The rails 172 and 174 may have screen holding flanges 184 and 186.

The top and bottom screen rails 188 and 190, FIGURE 5, may have respectively rollers 192 and 194 wit-h the rollers 192 engaging the top wall 22 and the rollers 194 engaging the bottom wall roller track 196.

The rollers 192 may be made removable so the screen panel may be changed to latch to the right frame jamb, as in FIGURE 1, or to the left frame jamb, as in FIG- URE 3.

However, if desired, entirely different screen panels may be used and substituted when the positioning of the panels 10 and 12 is changed from that of FIGURE 1 to that of FIGURE 3.

The side frame extrusions 16 and 18 may each have a base wall 24 having two outside flanges 40 and 42, and two inside flanges 30 and 38 with one of these flanges 38 having a seal receiving cavity 44.

The frame extrusion or sill20 may have three stepped walls 198, 200 and 202, with one of said walls 202 having the supporting roller supporting track 196 and with another of said walls 198 having the roller supporting track.

The bottom rail 140 of the movable panel 10 may be an extrusion and have a pair of central panel holding inward flanges 144 extendingupwardly, an intermediate wall 206 integral with flanges 144. It also may have outward, or downward, flanges 208 and 210 integral with wall 206 and extending in the opposite direction from flanges 144. The outward flanges 208 and 210 may have cavities 212 to receive inwardly directed seals 214 which may engage the sides of track 204. The seals 214 may be of the brush type, if desired.

The transverse wall 206 may be connected by screws 216 to a roller supporting frame which may include a horizontal wall 218 and vertical walls 220. The screws 216 may pass through wall 206 into wall 218.

The vertical walls 220 may carry the rollers 222 which may ride on the track 204.

The roller supporting frame may also include end walls 224, FIGURE 7, which may have screw receiving holes 226 threadedly to receive the screws 228 which may pass loosely through holes 230 in transverse wall 232 of the jamb rail 138 to secure the lower end of the jamb rail 138 to the bottom rail 140. The upper end of the jamb rail 138 may be secured to the head rail 136 by screws 234 which may pass loosely through holes 236 and threadedly engage the screw receiving channel 238 which is integral with the transverse wall 240 of the head rail 136.

The interlocking flanges 156 and 158 may be integral with and outside of the channel holding flanges 144 of the side rail 138.

The bottom rail 82 of panel 12 may be an extrusion which has a transverse wall 242 which is integral with the flanges 92, 94 and 98 and has the screw receiving channel 106 integral therewith. The rail 82 also has the seal receiving channels 100 and one or two seals 102 therein.

The pull rail 48 has a pair of central panel holding flanges 144 and a latch receiving cavity 244 upon which the flanges 144 are supported.

The glazing channels, such as channels 112, 114, 116, 118 and 120 each may have a pair of double inwardly directed flanges 246 and 248, FIGURE 6, with outwardly directed beads, such as 127 and 130 on each of the double flanges.

The glazing channels such as are shown for the stationary panel 12 in FIGURE 1 each has a pair of inwardly directed flanges 132 joined by a transverse wall 250. Each of the flanges 132 may have an end bead 127 and a pair of outwardly directed beads 130 parallel to the end bead 127. This arrangement of two outward beads 130 and an end bead 127 may also be applied to the double wall flanges 246 and 248 of FIGURE 6, and corresponding flanges of FIGURE 7. Such double wall flanges may also have a nintermediate wall 252.

The frame sill 20, FIGURE 5, may have the stepped walls 198, 200, and 202 connected to the transverse walls 254, 256, 258 and 260.

The top member 22, FIGURE 5, of the frame may have the main wall 262, transverse walls or flanges 264, 266, 268 and 270. The walls 264 and 266 may have seal cavities with seals 272, 274 and 276. The wall 268 may have the flange 278 to hold the wall 96.

The central panel holding flanges 60, 62, 88 and 90 of the rails 54 and 80 of the stationary panel 12 and similar flanges 144 of the side rails 48 and 138 of the movable panel are wider apart than thecentral panel holding flanges 84, 86, 92 and 94 of the top and bottom rails 78 and 82 of panel 12 and the corresponding flanges 144 of the top and bottom rails 136 and 140 of the movable panel 10. This enables the side rail flanges to dovetail over the top and bottom flanges at the corners of the panels 10 and 12.

The inward beads of the side rail flanges, such as 134 on side rail 80, FIGURE 6, are cut off at the ends of the rails so that the side rail channelholding flanges, such as 88 and 90 may dovetail over the top and bottom rail flanges 84, 86, 92 and 94. The similar beads on the panel holding flanges 60 and 62 on side rail 54, not shown in FIGURE 6, likewise are cut off for the same reason. Similar cutting of corresponding beads on the central panel holding flanges 144 of the side rails 48 and 138 of panel 10, FIG- URE 7, are similarly cut off for the same purpose as described in connection with FIGURE 6.

The glazed panels 108 and 142 may or may.not have the panel dividing or muntin construction 280 shown in FIGURE 5. The construction 280 may extend transversely of the panels.

The construction 280 may be an extrusionwhich includes a transverse wall 282 and glazing channel holding flanges 284, similar to flanges 84, 86, 90 and 92, elsewhere described, and each of which may have one or more inward beads 286 similar to the inward beads 134 elsewhere described. The glazing channels 288 may be similar to the glazing channels which are engaged by the top, bottom and side rails elsewhere described. These glazing channels 288 may be made to receive the double glazed construction shown in FIGURE 5, or they may be made to receive the single glazed constructions of FIGURES 6 and 7, as desired. The side rails, such as 54, 80, of FIGURE 6, and 48 and 138, of FIGURE 7, may have their inward beads 134 and 146 cut to receive the flanges 284 of the construction 280.

The closure construction may be made for the various combinations shown in FIGURES 1013.

FIGURE 10 shows a closure construction having a rightward openable panel, such as shown in FIGURES 3 and 4. FIGURE 11 shows a closure construction having 8 a leftward openable panel, such as shown in FIGURES 1 and 2. FIGURE 12 shows a closure construction having the closure construction of FIGURE 10 combined with an additional stationary panel on the left side of the closure construction. FIGURE 13 shows a closure construction in which the constructions of FIGURES 10 and 11 have been combined with the'construction of FIGURE 11 on the left side of the construction of FIG- URE 10. However, if desired, the construction of FIG- URE 10 can be placed on the left side of the construction of FIGURE 11, in a manner not shown but obvious from this disclosure. Also, two or more of the constructions of FIGURE 10 may be used side by side, or two or more of the constructions of FIGURE 11 may be used side by side, also not shown but obvious from this disclosure. Moreover, after installation, the relative positions of any of the pairs of movable and stationary panels may be changed, as previously described.

It is thus to be seen that a versatile construction has been provided. The movable panel 10 and the cooperating panel 12, which may be stationarily held if desired, may be selectively positioned as shown in FIGURE 1 or FIGURE 3. The panel 10 is leftwardly openable in FIGURE 1 and rightwardly openable in FIGURE 3, as viewed from the inside of the closure construction, that is, from the side which has the handle 24. The same panels 10 and 12 are usablein the positions of FIG- URES 1 and 3, by any positioning action desired, such as by rotating the panels 180 about vertical axes. The handle 24 and locking lever 26 are removable from and insertable in the pull rail 48 in the positions shown in FIGURES 1 and 3.

The panels 10 and 12 may be made from stock material to provide different sizes of panels, as desired.

The central panels 108 and 142 may be assembled from stock material to provide different sizes, as desired. These panels 108 and 142 may be singled glazed as in FIGURES 6 and 7 or double glazed as in FIGURES 1-5.

The clip 68, which holds one of the locking flanges 66, as shown in FIGURE 1, may be modified into the shape of the clip 310, which is shown in FIGURES 14, 15 and 16. The clip may have the general shape of that shown in FIGURE 1, except that a pair of grooved flanges 312 and 314 may be formed on such clip. These flanges may straddle the screw holes 316 in the main body of the clip 310. The holes 316 may receive screws corresponding to the screws 70 of FIGURE 1, which are indicated in dotted lines at 316 in FIGURE 14.

A name plate 320 may have its edges longitudinally inserted in the grooves of the flanges 312 and 314, as illustrated in FIGURE 14, and this will conceal the screws 70 of FIGURE 1 which are inserted in the holes 318.

Any number of clip members 310 and name plates 320 may be placed along the vertical edge 16 or 18, where desired.

The name plate 320 may be ornamental, as shown, and may have any desired name or symbol formed thereon, as shown. This provides an ornamental finish to the door frame construction, and conceals the attaching screws in holes 316 and any other holes that may be formed in the clip 310.

FIGURES 17, 18 and 19 illustrate a construction which is used with the removal of the upper portions of the flanges 152 and 154, and the sealing strips 170, FIGURES 1 and 6, which are carried thereby, so that the fixed panel 12 may be lifted upwardly to remove it from the door frame.

FIGURE 17 shows a portion of FIGURE 6, and illustrates the upper end of the meeting rail 80, with its flanges 88 and 90. These flanges 88 and have the interlocking flanges 152 and 154 with tapered ends 166. Both of the flanges 152 and 154 are illustrated in FIGURE 1. Only flange 152 is visible in FIGURE 17. The tapered ends 166 of both flanges 152 and 154 are visible in dotted lines in FIGURE 18. These flanges carry the sealing 9 strips 170, to prevent air from flowing into the room from the outside and vice versa.

However, it is desirable to remove the upper portions of the flanges 152 and 154, with their sealing strips 170 and with their tapered edges 166 at the upper parts of the meeting rail 80, so that the panel 12 which carries these flanges 152 and 154 can be lifted upwardly for removal of the panel 12 from the door frame. These flanges and sealing strips 170 may be removed (in a manner not illustrated) from about the axis line 320 of screw 109, in FIGURE 17, to the upper edge 322 of the meeting rail 80. This removal destroys the sealing action at the upper end of the rail 80, and produces a void or break in the sealing strips since such removed portions extend below the lower edges of the flanges 268 and 266 which are shown in FIGURE down to the level of the screw receiving channel 104 at the top of FIGURE 5 and down to the screw axis 320 of FIGURE 17. That is, the flanges 152 and 154, edges 166 and sealing strips 170 are removed from the edge 322, FIGURE 17, to the axis line 320. To prevent undesirable drafts through such void or break in the sealing action, two substitute seal carrying clips 324 and 326 may be secured to the upper corner of the meeting rail 80, as shown in FIGURE 18, after the panel 12 is installed in the door frame. The holes 328 of the clips 324 and 326 are placed over the head of the screw 109. A new screw 330 is inserted in the aligned holes 332 of the clips 324 and 326. A new screw receiving hole may be drilled in the meeting rail 80 to receive the new screw 330. The clip 324 carries a substitute seal construction 336 for filling part of the void producd by the removal of part of the sealing strip 170. The clip 326 carries a similar substitute seal construction 338. These seal constructions 336 and 338 are in alignment with the sealing strips 170 which are present in the flanges 152 and 154,

and they form substitute seals for the removed portions of such sealing strips 170. These constructions 336 and 338 form continuations of seals 170 and extend a suflicient distance upwardly, to produce a substantial seal up to the lower edges of the flanges 266 and 268 of FIG- URE 5.

The clips 324 and 326 are made similar to each other. They can be placed on opposite sides of the meeting rail 80 as illustrated in FIGURE 18. Extra holes 332 are drilled in each clip 324 and 326. Hence, the clips 324 and 326 may be reversed when they are applied to the panel 12 when such panel has been reversed to the position of FIGURE 3 from the position of FIGURE 1.

A new and useful closure construction and method of making the same have been provided.
